30-50 is old now? I guess I'm just not in the right scene. And no, I never was in the swinging or lifting/roiding scene (although now I do take testosterone), really, properly speaking. But it used to be around with a fair degree of ubiquity in party scenes in general even after the initial ban, although part of this was because the precursors and analogs were easy to deal with and lots of people in those scenes for lots of years were doing GBL, whatever they thought they were taking; but although as I said I don't party any more I'm still surprised to hear that it's common. I remember being pretty excited, along with some other very well-informed friends, something around ten years ago when we got real, unfucked-with GHB in that waxy sort of state; readily dissolvable but that's the stuff you want, the liquid is probably more likely to be GBL or, worse, 1,4-BDO, but your tastebuds would probably know, although all of the shit tastes horrible to me.
The really quite offensive brackish taste of GHB always kind of made me suspicious of the ideas of people slipping it into people's drinks unawares—the whole "date rape drug" thing was a classic moral panic hysterically overdone by the media and most of it just doesn't stand up to scrutiny by people who actually know about drugs—flunitrazepam is the likeliest case of course but is still also questionable and definitely really not much more efficacious than any other strongly sedating and/or disinhibiting benzodiazepine (depending on what we're talking about)—and
ketamine? also has an offputting taste, but requires pretty large amounts to be especially effective and would not easily be mistaken for alcohol—but GHB, GHB in particular doesn't strike me as particularly plausible; hell, I tried mixing it with just about whatever to try to make it easily palatable, but mostly just wound up swallowing little bits of the wax stuff or measuring mLs of GBL (which, also, I couldn't stand the taste of, but would usually put in orange juice in a shot glass and then a big glass of OJ as a chaser), again, I don't know how it possibly could've gotten into anyone's drinks without alarm bells going off, although I don't know about super sweet fruity cocktails and such, so maybe the best HR advice on that front would be to just keep drinking martinis
But "smoke" 'em if you've got 'em, GHB is a hell of a lot of fun, if done safely (spoiler alert it can kill you etc) and can be super-addictive (there was a time when a shitton of BLers were strung out on [it, but especially GBL], as seems to be the way of things around here, these little trends, GHB,ketamine, mephedrone, RC benzos, fentalogues, whatever, there's always a drug-of-the-moment that's addicting/killing people around here.)
